I have mercury 4 stroke 75
I have same questions
I dont have a dealer near so im going to
order my filter/oil on line

The drain plug is about half the way down the shaft just above the foot. You can miss it on the side. I use the Mercury 4 stroke oil but all my friends use a good synthetic out like Castrol or equal. I was scared to try at first but after I did it was so easy.

You should be able to just take the filter to an autoparts store and they will be able to match it up for you

i just got the toon home and startting to work on it thanks for the help

You should be able to get the tech specs on the manufactuers website
